ble app uart problems

[serzh]

hi i have a problem with ble app uart.i used nRF5_SDK_12.3.0_d7731ad and Eclipse Mars 2. I had build main.c in hex ble_app_uart\pca10040\s132 . And after that a maked mergehex with s132_nrf52_3.0.0_softdevice.hex.i flashed into my BLE nitrogen. i can conect to BLE. But any messages what i sended on Bluetooth from my Phone Do not return in my phone but function can do it.And more when i put in condition code for togle blinky i had not any bkinky when i sended mesage from my phone

void uart_event_handle(app_uart_evt_t * p_event)
{
    static uint8_t data_array[BLE_NUS_MAX_DATA_LEN];
    static uint8_t index = 0;
    uint32_t       err_code;

    switch (p_event->evt_type)
    {
        case APP_UART_DATA_READY:
            UNUSED_VARIABLE(app_uart_get(&data_array[index]));
            index++;

            if ((data_array[index - 1] == 'q') || (index >= (BLE_NUS_MAX_DATA_LEN)))
            {
                //send mesage as resived
                err_code = ble_nus_string_send(&m_nus, data_array, index);
                if (err_code != NRF_ERROR_INVALID_STATE)
                {
                    APP_ERROR_CHECK(err_code);
                }

                index = 0;
            }
            break;

        case APP_UART_COMMUNICATION_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_communication);
            break;

        case APP_UART_FIFO_ERROR:
            APP_ERROR_HANDLER(p_event->data.error_code);
            break;

        default:
            break;
    }
}

When i modified main

int main(void)
{
    uint32_t err_code;
    uint8_t dat_array[5]={'a','a','a','a','a'};
    bool erase_bonds;
    // Initialize.
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
    uart_init();

    buttons_leds_init(&erase_bonds);
    ble_stack_init();
    gap_params_init();
    services_init();
    advertising_init();
    conn_params_init();

    printf("\r\nUART Start!\r\n");
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
   	nrf_gpio_cfg_output(29);
    // Enter main loop.
    for (;;)
    {
    	ble_nus_string_send(&m_nus, dat_array, 5);
    	nrf_delay_ms(50);
        power_manage();
    }
}

i had mesage on my phone

i want to now how i can resive msg from my phone where is exampe or can you help me?

i modified function for it

static void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length) 
{ 
    for (uint32_t i = 0; i < length; i++) 
    { 
        ble_nus_string_send(&m_nus, p_data,length); 
        // while (app_uart_put(p_data[i]) != NRF_SUCCESS); 
    } 
    // while (app_uart_put('\r') != NRF_SUCCESS); 
    // while (app_uart_put('\n') != NRF_SUCCESS); 
}
